CROSS REFERENCE TO RELATED APPLICATIONS

This is non-provisional patent application related to U.S. patent application Ser. No. 12/243,111 titled “Coordinated Management In Virtualized Systems Using Management Brokers And Management Channels” that was Filed on Oct. 1, 2008, and which is incorporated by reference in its entirety.

BACKGROUND

Service processors are processors, or other types of integrated circuits, that are used to manage or co-manage, alongside or part of one or more general purpose processors, specific functionality in a computer system. This functionality may include computer system diagnostics, power resource management, and remote computer system configuration and management. There is no direct communication between service processors, that is the service processors are horizontally and/or vertically silo-ed. Some example service processors include Hewlett-Packard Company's INTEGRATED LIGHTS OUT™ (iLO) series of service processors.

Vertically silo-ed means that a separate infrastructure exists for monitoring the hardware, virtualization, and application stacks. Horizontal silo-ed means that there is no direct communication among the peers, as a result the aggregation and correlation is performed at a centralized location. A peer is a service processor. This central location may be a management computer system or management blade.

Monitoring may involve the use of various hardware (HW) and/or Software (SW) stack sensor and actuators that monitor the functionality of the HW/SW stacks. These sensors and actuators may be used in the aforementioned computer system diagnostics, power resource management, and remote computer system configuration and management.

DETAILED DESCRIPTION

Illustrated is a system and method for resource management for unified and automated monitoring across the hardware and software stacks in a distributed system. This system and method may be used to manage vertically and horizontally silo-ed HW/SW stacks. Manage, as used herein, includes recording and making available for display sensor and actuator data relating to the HW/SW stacks. The overall system and method includes: (i) federated registry and proxy services for automating the discovery of sensors and actuators across HW/SW stacks and node boundaries and dynamic routing of queries to these sensors and actuators; (ii) distributed brokers for executing monitoring correlation and aggregation policies in a scalable manner. The system and method is instantiated in the service processor and in a special virtual platform appliance on every node.

FIG. 1 is a block diagram of an example architecture 100 illustrating the hierarchical organization of the various components that make up the hardware stack. Shown is a core 107 that resides, along with other cores, as part of a socket 106. This socket 106 is, in turn, part of an enclosure 101. The enclosures 101-103 are part of a rack 104. An example an enclosure 101 or 102 is a compute blade. The rack 104 is part of a container 105. The container 105 is part of a data center 108.

FIG. 2 is a block diagram of an exploded view of an example socket 106 that includes the service processor. Shown is the socket 106 that includes at least one Central Processing Unit (CPU) 201. Residing on this CPU 201 is a SW stack 203. Also shown is a service processor 202 that is co-located on the socket 106 with the CPU 201. In some example embodiments, the service processor 202 and CPU 201 are associated in a one-to-one or one-to-many relationship. This service processor 202 may be a CPU, accelerator, Graphical Processing Unit (GPU), or other suitable processor. Residing on the service processor 202 is firmware 204.

FIG. 3 is block diagram of an example software stack 300 for a system and method for resource management for unified and automated monitoring across the hardware and software stacks in a distributed system, the monitoring occurring in a virtualized environment. Shown is a hypervisor 301, guest Virtual Machine (VM) 302. Dom0 303, and service processor helper 304 that collectively make up the SW stack 203. The hypervisor 301 may be an XEN™ hypervisor, or other suitable hypervisor. The service processor helper 304 may reside as part of the guest VM 302 or the DOMO 303, or be a separate module that resides on the hypervisor 301. Residing as part of the guest VM 302 is an OS 305, Service Level Agreement (SLA) sensor and actuator 306, and an application 307. The OS 305 may be a LINUX™, WINDOWS™, or another suitable operating system. The SLA sensors and actuators 306 may be an application that monitors SW stack performance to ensure that it is consistent with the terms of a SLA covering SW stack performance. This SW stack performance may include execution times associated with the application 307, or other performance information related to the application 307. The application 307 may be a map-reduce, social networking, e-commerce solution, multitier web applications, video streaming, or other suitable application. In some example embodiments, a plurality of guest VMs 302 may reside on the CPU 201. Included as part of the Dom0 303 is a virtualization sensor and actuator 308 that is used by the Dom0 303 to monitor the various guest VMs 302 and their respective performance. The performance issues related to the guest VM 302 may include memory utilization issues associated with the guest VM 302.

Further illustrated, is the service processor helper 304 that acts as a platform virtual appliance to allow the service processor 202 to manage the HW/SW stack of the CPU 201. Shown is the helper registry and proxy services 310 that is responsible for the: (i) auto-discovery of sensors and actuators across the HW/SW stack, (ii) subsequent registration of the individual namespaces of these sensors and actuators, and (iii) once registered, doing a dynamic redirection of query calls (i.e., proxy functionality) to the appropriate sensors and actuators in the socket 106. On top of the helper registry and proxy services 310 exists a helper broker 309 responsible for executing, monitoring correlation and aggregation policies in a scalable and coordinated manner. These policies relate to one or more of the guest VM 302. The helper broker 309 and helper registry and proxy service 310 are used to resolve vertical silos across the HW/SW layer of the CPU 201 (i.e., a local domain) through the monitoring of sensors and actuators within the management domain of the CPU 201. This registration process may be repeated periodically using a lease-based mechanism so as to support dynamism occurring in the system (e.g., VMs entry/exit/migrations, HW upgrades etc.).

Additionally shown is the firmware 204 that includes the console 311, service processor broker 312, service processor registry and proxy services 313, and platform sensors and actuator 314. The console 311 allows users of the system and method illustrated herein to monitor and manage the HW/SW stack of, for example, the enclosures 101-103 through the use of a dashboard, GUI, CLI, internet browser, or other suitable interface. This console 311 facilitates this management capability through the use of a network connection 315 that utilizes a protocol such as a Hyper Text Transfer Protocol (HTTP). Also shown is a service processor broker 312 responsible for executing, monitoring correlation and aggregation policies in a scalable and coordinated manner. These policies relate to one of more hypervisors 301. Further shown, is a service processor registry and proxy service module 313 that is responsible for discovering and registering the sensors and actuators in the distributed system along with their meta-data. This module 313 is also responsible for dynamically proxy-ing query calls to appropriate sensors and actuators in the distributed system through the use of the network connection 316. The network connection 316 may be a logical or physical connection. Also shown is a platform sensors and actuators, actuator 314 that includes sensors and actuators used to monitor the service processor 202. The service processor broker 309 and service processor registry and proxy service 310 are used to resolve vertical and horizontal silos across the HW/SW layer of the socket 106, enclosures 101-103, rack 104, container 105, and/or the data center 108 (i.e., collectively remote domains) through the monitoring of sensors and actuators within the various management domains of each of these aforementioned devices.

In some example embodiments, the use of sensors and actuators in the management of the HW/SW layer of these various domains is facilitated through the use of distributed registry functionality. Specifically, a local registry table is maintained by the helper broker 309 and helper registry and proxy services 310. This local registry table is federated or combined with other local registries tables from other service processors using a distributed overlay, wherein the service processors are operatively connected via the network connection 316. Using the network connection 316, the proxy functionality is provided in the system and method by dynamically routing queries in the distributed overlay, and from, for example the service processor 202 to any CPU management domain on a socket, node, or enclosure via the service processor helper 309.

FIG. 4 is a diagram of an example software stack 400 for a system and method for resource management for unified and automated monitoring across the hardware and software stacks in a distributed system, the monitoring occurring for a single operating system. Shown is a CPU 401. Residing on top of the CPU 401 is a single OS 402. Residing as part of the single OS 402 is a service processor helper 403. The service processor helper 403 includes a helper broker 404 and a helper registry and proxy service 405. The OS 402 also includes an application 407 and SLA sensor and actuator 406. Data for the CPU 401 and software stack data for the OS 402 may be retrieved using CIMOM in combination with the previously illustrated service processors broker 312, service processor registry and proxy service 313, and platform sensor actuator 314.

FIG. 5 is a diagram of an example console 311 in the form of a GUI used to monitor and manage the HW/SW stack of a plurality of domains. The plurality of domains include HW/SW stacks associated with a cloud. Shown is a unified system status tab 501 that, when executed, displays both HW and SW stack sensor and actuator information for both a local and remote domains. For example, various tabs relates to the NW stack are illustrated, where these tabs display data (i.e., HW stack data) for sensors and actuators related to the system (e.g., the CPU 201), fans, temperatures, power, processors, memory and the Network Interface Card (NIC). These tabs are collectively referenced at 502. Also shown are tabs related to the SW stack and display data (i.e., SW stack data) related to hypervisors and VMs. These tabs are collectively referenced at 503. HW stack data is displayed in a field 504. Hypervisor data is displayed as part of the field 505, while VM data is displayed as part of field 506.

FIG. 6 is a block diagram of an example architecture 600 used in the discovery and monitoring of sensors and actuators with a local domain. Shown is the service processor registry and proxy services 313, helper registry and proxy services 310 and Dom0 303 that are used together to construct the local registry table. The helper registry and proxy services 310 may reside as part of a guest VM 302. In some example embodiments, the helper registry and proxy service 310 executes an internal discovery of management domains (e.g., the guest VM 302, hypervisor 301, and the CPU 202) for that node. It is assumed, for example, that a Web Services-Management (WS-Man) endpoint exists in each management domain(s). In some example embodiments, some other type of protocol may be implemented in lieu of WS-Man. These other types of protocols may include Customer Information Manager/eXtensible Markup Language (CIM/XML), Distributed Component Object Model (DCOM) or Server Management Command Line Protocol (SM CLP). This internal discovery takes place using, for example, SLP (Service Location Protocol).

In one example embodiment, a local registry table is built and maintained as part of a helper registry 604. The data that populates this helper registry 604 may be metadata and/or actual data that identifies management endpoints (e.g., Dom0, guest VMs, or platforms) via a discovery protocol. This discovery protocol may be SLP, Ping Sweep, Web Service (WS)-identify, Domain Name Server/Dynamic Host Control Protocol (DNS/DHCP), or some other suitable protocol. This data is stored in the helper registry 604. Discovery of the management endpoints (e.g., WS-Man) may be conducted using a SLP User Agent (SLP UA) 605 that resides on the Dom0 303 and guest VM 302 and which receives queries from an internal discovery service (SLP SA) 603 that resides as part of the helper registry and proxy services 310. A multicast channel is assumed for the SLP-based discovery of VMs, and Dom0. In order to limit the multicast message to the management domains in that node only, a firewall rule may be introduced in Dom0 303 to drop the forwarding of the message outside of the node. Once the discovery of the management end points by the helper registry and proxy services 310 occurs, a namespace registration occurs using the namespace registration module 602 to query the CIMOM of each WS-Man endpoint 606. Where a namespace is established for each sensor and actuator, the helper registry and proxy service module 310 queries each WS-Man endpoint for each CIMOM to retrieve the namespaces associated with a VM, Dom0, platforms, or other suitable devices and components. Additional processing (e.g., filtering) may be performed on the retrieved namespaces. Further, the discovery of the management endpoints (e.g., WS-Man) at the hardware/platform layer is done by the service processor registry and proxy services 313. The helper registry and proxy services 310 queries the service processor registry and proxy services 313 to retrieve the hardware discovery information, then to populate the helper registry 604 with this discovered data.

FIG. 7 is an example helper registry 604 that includes data for a local domain. Shown are columns 701-704, wherein column 701 includes data for a type of management domain 701, column 702 includes data for addressing a particular management domain, column 703 includes a description for a domain, and column 704 includes a description of a data structure used to access the domain. Regarding column 701, this column includes data relating to the type of management domain, where this domain may be a service processor, Dom0, guest VM, or other suitable domain. Column 702 includes data for addressing a domain, where this address may be an Internet Protocol (IP) address, Media Access Control (MAC) address, Uniform Resource Identifier (URI), or other numeric or alpha-numeric value used to uniquely identify a management domain. The data for column 702 may be retrieved from the WS-Man associated with each of the service processor, Dom0, or VMs. Column 703 includes a description of a management domain, where this description may be versioning information, trade name information, or other suitable information. Column 704 includes namespace registration information retrieved from CIMOM. As is illustrated above, the data included in the helper registry 504 may be displayed as part of the console 311.

FIG. 8 is a block diagram of an example architecture 800 used in the discovery and monitoring of service processor peers within an enclosure, other remote domains. Shown are plurality of enclosures 102-103 that each includes service processors 202, and service processor registry and proxy services 313. Using an external discovery module 803, the other peer service processors can be discovered. In some example embodiments, a multicast/broadcast based mechanism, illustrated at 805, is used amongst the service processor registry and proxy services 310 that resides as part of the service processor helper 304 for each peer to discover each peer. Discovered information is returned (e.g., a broadcast response) that includes, for example, an Internet Protocol (IP) address, Domain Name Server (DNS) name, and/or port value. This discovered information will be placed into a routing table 807. The routing table 807 is used to dynamically route queries from a receiving service processor to a peer service processor. In some example embodiments, the external discovery and external routing can be handled using a distributed overlay such as a Distributed Hash Table (DHT). A distributed overlay can be used by the service processor registry and proxy services 313 to enables each individual service processor to access data from peer service processors and the helper registries associated therewith. Using a data structure such as a array, list, matrix, lookup table or DHT the external routing and proxying module 801 can route a query to the appropriate service processor registry and proxy service 313 of the enclosure 102 using the network connection 316. For example, if a request is made from a service processor of an enclosure or node to access the hypervisor data on another enclosure or node, the DHT is used to route the query through the service processor registry and proxy services module 313 to the service processor of another enclosure or node. The query is then proxy-ed through the service processor helper 304 of that node or enclosure to the CIMOM 507 in Dom0 303 of that node or enclosure. The response may be returned back via the same path. In some example embodiments, the service processor registry and proxy module 313 helps in the proxying of calls to other peer service processors, and also redirects calls to service processor helpers for access to data from individual CPU management domains (e.g., guest VMs, Dom0). This redirecting of calls may be facilitated through the use of the network connection 806. In some example embodiments, the registration process is repeated periodically using a lease-based mechanism so as to support dynamism occurring in the system (e.g., VMs entry/exit/migrations, HW upgrades etc.). The internal hardware discovery module 802, stores the discovered hardware management endpoints that include WS-Man endpoints associated with the service processor 202. In some example embodiments, the discovery of hardware management endpoints can be performed using the Platform Management Components Intercommunication (PMCI) standard. The information/data in the internal hardware registry 808 can be provided to the helper registry and proxy services 310. When a query is received by the service processor, the service processor determines whether the query is for “this” (i.e., the receiving) processor. If not, then the external routing and proxying module 801 accesses the routing table 807 to determine which service process or to which to forward the query.

FIG. 9 is a sequence diagram illustrating an example method 900 for distributed monitoring across the HW/SW stacks. The steps shown are in response to a query at one of the service processors 202 in a distributed system to provide/display aggregated data across HW/SW stack for an enclosure. This includes data from the individual hardware in the enclosure, but also data from software that includes the hypervisor, and individual guest VMs. Shown are the service processor broker 312, service processor Software Development Kit (SDK) 902, and service processor registry and proxy service 313 each of which resides on the service processor 202. Also shown are the service processor helper registry and proxy service 310 each of which resides on the CPU 201. These various modules are executed as part of the method 900. Further, as denoted at 912 and 913, the discovery of peer service processors and managed domains may occur on a continuous basis that is repeated periodically using a lease-based mechanism so as to support dynamism occurring in the system (e.g., VMs entry/exit/migrations, HW upgrades etc.).

In some example embodiments, a query is received by the service processor broker 312. The service processor broken 312 uses the service processor broker SDK 902 and the service processor registry and proxy service 313 to handle the query. The service processor broker SDK 902 may be accessed using the following Application Programming Interfaces (APIs):

int getManagedDomains(domainList&); int getManagedDomains(domainList&, domainFilter&); int getManagedDomains(domainList&, string); int getSensorsList(sensors List&, string, int); int getActuatorList(actuatorList&, string); int callActuator(string, string, string, actuatorParamList&, actuatorParamList&); int registerSensor(string, string, string[ ], int, int, void (*callFunction)(sensorData&)); int unregisterSensor(string, string); int unregisterSensor(int). At 905, the service processor broker 312 calls the SDK APIs to list the local managed domains. The SDK, in turn, makes calls to the service processor registry and proxy service 313 to obtain the requested information. The service processor registry and proxy service 313 makes calls to the service processor helper registry and proxy services 310 to return the requested information from the CPU (e.g., CPU 201). As shown at 906, a list of peer brokers can be provided by the service processor broker 312 in response to a query. Illustrated at 907 is a list of managed domains of a particular peer service processor that can be provided in response to a query. The query may be re-directed via the network connection 316, acting as a broker channel, to another peer service processor. The sequences shown at 905-907 may utilize registry information from the internal hardware registry 808 and the routing table 807. Shown at 908 is a list of sensors and actuators for a domain managed by a service processor, the list of sensors and actuators provided in response to an initial query. The query may be re-directed via the network connection 316, acting as a broker channel, to another peer service processor. This list of sensors and actuators may be provided to both the service processor registry and proxy service 313 and the service processor helper registry and proxy service 310. The sequence illustrated at 909 shows a list of sensors and actuators managed domains of peers of the service processors responding to the query. This list of sensors and actuators is provided via the network connection 316 acting as a broker channel. The sequences shown at 908 and 909 may use a namespace based query to obtain the list of sensors of the managed domain, and the list of sensors managed domains of a peer. Shown at 910 is local managed sensors and actuators domain data that is retrieved in response to a query. Further, using this data, the service processor registry and proxy service 313 may contact the sensors and actuators on the domain managed by the service processor responding to the query. Further, as shown at 911 domain sensor and actuator data managed by a peer service processor may also be retrieved. The sequences illustrated at 910 and 911 may use a method associated with the namespaces to get the requested data. As illustrated at 912, the data retrieved at 910 may be aggregated and compiled for future use and analysis.
